Full-Stack AI Engineer enterprise AI platforms, intelligent document automation, scalable architecture
Qatar / India · Open to remote
I build production-grade React/FastAPI systems around LLM and RAG pipelines semantic and graph-based retrieval, vector databases, cloud-native APIs and enterprise knowledge platforms and own the architecture decisions that keep them fast and maintainable.
Recent shipping surface:
- Enterprise AI architecture LLM/RAG pipelines, semantic search, pgvector, graph-based retrieval and knowledge indexing for a production SaaS platform
- Intelligent document automation extraction, chunking, retrieval evaluation over real document estates, measured in retrieval time cut
- Computer vision at scale YOLO/TensorFlow inference across a 1,100-camera security deployment
- Full-stack delivery React / FastAPI / PostgreSQL / Docker on Azure, shipped through GitHub Actions and tested with Playwright
Currently going deeper on agentic AI, Kubernetes, and evaluation tooling for RAG.
Mar 2026 – Present
- Core contributor to AgileWriter, an enterprise AI document automation platform full-stack delivery across React, FastAPI, Python, TypeScript, PostgreSQL, Azure, Docker, Microsoft Graph, Redux Toolkit and TailwindCSS.
- Designed scalable AI architecture: LLM/RAG pipelines, semantic search,
pgvector, graph-based retrieval and enterprise knowledge indexing, enabling faster storage, retrieval and contextual reasoning across enterprise knowledge bases. - Led architectural decision-making through Engineering Design Reviews, API design, system architecture documentation, performance optimisation, authentication architecture and reusable engineering standards for a production-scale SaaS platform.
- Also shipping a high-security LLM assistant for banking FAQs and Playwright UI automation coverage.
Nov 2025 – Mar 2026
